B'. WALKER LIQUID BOMB Feb. 25, 1947.

Filed May 17, 1945 WciM/malw Patented Feb. 25, 1947 UNITED STATES PATENT OFFICE (Granted under theact of March v3., 1883, :as amended April .30, 1928; v3.70 O. G. 757).

Claims;

The invention described herein may be manu;-

iactured `and used by or tor the Government for the bomb and then to effect prompt mixing andY time delay operation.

The mixing is accomplished by gas pressure from an explosion or from the puncturin'g of -a charged gas cylinder which forcesthe liquid from one `chamber into the other chamber and 4gives agitated mixingr prior to detonation, The seals are broken by `pressure to permit the mixing and are safe against leaking during storage.

Other features of the invention will be more particularly pointed out in the attached specification, claims, and drawings in which:

Fig. 1 is a side elevation partly in section of one form of my invention.

Fig. 2 is a partial side view of the upper portion of a bomb mechanism employing another form of my invention.

Fig. 3 is a partial View of the upper section of the bomb mechanism shown in Fig. 1 prior to operation.

Fig. 4 is a cross vertical section through 4--4 of Fig. 1.

Fig. 5 is a cross vertical section through 5 5 of Fig. 1, and

4Figure 6 is a fragmentary detail sectional View of the upper portion of the firing pin housing, shown in normal position the means for holding the ring pin inoperative until impact of the bomb.

In all figures like numerals of reference refer to corresponding parts of the various views.

In Figs. 1, 3, 4 and 5, I have shown a bomb having a case lll a relief valve l2 located in the side thereof and a tail iin assembly Il, The bomb is filled with two liquids in the cavities 40 and 5b which separately are safe against explosion but, when mixed, form a powerful explosive such as nitro tetra oxide. Benzine or gasoline or other hydrocarbons in association with an oxide of nitrogen, the same being generally known as anilite explosives, may be employed, or any other combination of -liquids forming an explosive or. toxic substance when; mixed.

The mechanism for performing the mixingV op eration. is as follows:

Apropeller 20 isretained inthe bomb rack by the usual arming wire 5| usually carrying some clips-52 to prevent accidental withdrawal in handling. When dropped, this'wireis withdrawn and the air stream rotates the* propeller 20 to unscrew the stem 2| from. thering pin 23 in housing 23'. The spring 2,:2 forces the firing pin 23 against the primer of the blank cartridge .2d which forces plunger 26 down `against the pressure .chamber to puncture the diaphragm on the. lower end thereof by the sharp hollow needlev 28. The pressure cylinder. is in a container i6.. The Aplunger' 23 acts asa valveto prevent escape of the gas after the cylinder is punctured. The gas pressure breaks the seal `29 in the needle 28. and` allows the gas to enter the cavity where liquid 40 is` stored. This pressure bursts the seals |5a inthe lower diaphragm |522 of the container I5. The gas pressure forces the liquid Ml out through these ports 15a to .mix with the liquid in the outer chamber. After the liquid 110 has been forced out of its container into mixture with liquid 50 an agitation of the two liquids is continued for a short time by the gas from the inner chamber bubbling up through the mixed liquids.

On impact with the bombs the base detonating fuse which is armed by the forcing down of the pressure chamber 35 acts to detonate the mixed liquids. Excessive pressure is released through the pressure relief valve I2. Details of the base detonating fuse are not shown as many types are known that `can be armed by the motion of a control rod 38. Fig. 3 shows this construction in its position prior to dropping.

Fig, 2 shows a `delayed action tail assembly. The propeller 20 unscrews screw 2l from ring pin 23 but does not release it due to the shear pin 41 that passes through the firing pin and wall of a tubular extension on the underside of the top of the housing 23 and retains the iiring pin until the jar of impact with a target when the ring pin acts and mixing of the liquids follows as described in connection with Figs. and 3. The base fuse in this case is a time delay fuse actuated by the action of the pressure cylinder 35 through a control rod 38. The time fuse functions after the mixing takes place to perform for ship bombing with the required time delay or for demolition.

When a bomb of this type goes through a 4. The invention of claim 1 characterized in that the fracturable means on the component container is located at the end of the component container opposite the pressure chamber.

5. In a bomb, a hollow body containing a liquid component of an explosive, a normally sealed container in said body containing another explosive component which in union with the rst, forms an explosive compound, a pressure chamber in the normally sealed container in gas tight relation to Y the contents of said container, a gas filled concomponent of an explosive, a normally sealed container in said body containing another explosive component which in union with the first forms an explosive compound, a pressure chamber in the component container normally in gas tight relation to the contents of the container, a gas filled movable container in said chamber, 'a fran# gible seal for said gas container, a hollow puncturing pin having a rupturable seal therein and positioned to puncture said frangible seal upon the axial movement of the gas container to establish communication between the gas container, the pressure chamber and the component container, fracturable means on the component container and rupturable by the pressure of the contents of the component container, and means operable during the flight of the bomb to move the gas container relative to the punching pin to puncture the frangible disc.

2. The invention of claim 1 characterized in that the means operable during the flight of the bomb to move the gas container relative to the punching pin comprises a plunger mounted in a bore in the top of the pressure chamber and having a portion adapted to engage the gas filled container, a blank cartridge in the bore positioned to move the plunger upon detonation of the cartridge, a spring restrained ring pin arranged to contact the cartridge, and propeller means adapted to release the firing pin during the flightof the bomb.

3. The invention of claim 1 characterized in that the explosive component contained in the normally sealed container, is gaseous.

tainer in the pressure chamber, means for placing the hollow body, sealed container, pressure chamber, and gas` filled container in communication, a closure for the pressure chamber having a bore therein, a plunger slidable in said bore and having a part adapted to contact the gas iilled container, a cartridge in the bore adapted, upon detonation, to give impulse to the plunger, a spring restrained firing pin, dual means for locking said ring pin in inoperative position, and a device operative during night to render one of said means inoperative, the other of said means being operable upon impact to release the firing pin.
